Railway vehicle end door driving mechanism

Abstract

The invention provides a railway vehicle end door driving mechanism. The railway vehicle end door driving mechanism mainly comprises a driving mechanism, a rebound unit, a driving arm assembly, a synchronous rope mechanism, an electromagnet, a guide rail and a position switch, the driving mechanism is connected with a door plate and the synchronous rope mechanism, the upper end of the driving arm assembly is connected with the rebound unit, the lower end of the driving arm assembly is connected with the door plate, the rebound unit is used for enabling the driving arm assembly to drive the door plate to move to achieve automatic door closing in emergency, the position switch is used for detecting whether the door is opened in place or not, and the electromagnet is used for attracting the door plate when the door is opened in place. During normal operation of a vehicle, a door leaf is in an open state, the door leaf is kept in an open position through attraction of the electromagnet, the door system in the open position stores energy in a spring in the rebound unit, when a fire disaster or other emergency situations occur, the electromagnet is powered off and loses attraction force, and the door plate is automatically closed under the tension action of the spring.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle end door control, and in particular relates to a fireproof end door driving mechanism. Background technique [0002] In the existing rail vehicle structure, there are usually two types of inner end doors and outer end doors at the end of the vehicle. The outer end doors are mainly used for fire prevention, and the inner end doors are ordinary compartment partition doors to meet specific operational requirements. The outer door is set in order to meet the fire protection requirements of the vehicle. This door needs to be kept open during normal operation to ensure an open passenger environment and facilitate the passage of passengers between the compartments. At the same time, in the event of a fire, when the vehicle is not charged, the door needs to be automatically closed to form a fireproof partition to ensure the safety of passengers. However, in the past, the outer end doors were normall...

AI Technical Summary

Problems solved by technology

However, in the past, the outer end doors were normally closed end doors, and the opening and closing of the door was realized by a motor. For the normally closed fireproof end doors, each time passing through the end of the carriage, the door needs to be opened and then closed. The normal passage and escape of passengers between the compartments cannot effectively guarantee the safety of the vehicle
